Omron E3FA-LN11 2M is a pre-wired NPN background-suppression sensor with 100 mm red-light range, 0.5 ms response and IP67/IP69K.
The Omron E3FA-LN11 is a straight-type background-suppression photoelectric sensor with NPN output and 2 m pre-wired cable. Omron specifies a 100 mm sensing distance on a 300 × 300 mm white target, a 624 nm red LED, a one-turn sensitivity adjuster, selectable Light-ON/Dark-ON operation, 0.5 ms response and IP67/IP69K protection. Current supply status is not established by the consulted manufacturer material and is recorded as Unknown.

Engineering suggestions require suitability checks for your installation.
The sensor may need to detect a target while reducing switching caused by objects behind the target.
The 100 mm background-suppression mode can be evaluated with the actual target and background geometry; set sensitivity and verify the switching boundary.
A fixture may need to confirm a workpiece without responding to nearby mounting surfaces.
Use the one-turn sensitivity adjustment and selectable output logic after checking target color, distance and mechanical alignment.
